Applet SMUDGES on rapid/steady scrollbar movement...

Running into a problem with an applet smudging outside the "Applet Container." The java code was kept to the JDK 1.0 standards for compatibility with older browser and to minimize code size.
The applet is designed to display a list box type format on a web page--dynamically populated--and to allow click-throughs.
The problem arises when you move the scrollbar around and the applet "smudges" onto the immediate area around the applet. I have taken a picture of the applet PictureLynxx in case it cannot be duplicated on your system-- http://images.auctionhelper.com/images/bwilkins/PictureLynxx_Smudge.jpg --you will see the top 30 pixels are actually not aligned with the bottom half becuase they were "smudged" and hense not updated or repainted by the browser. I have seen this happen with IE, Netscape and every flavor of OS. Not sure how to move forward from here. Any help or comments are appreciated.
Here is a live sample of the applets for your own testing:

Thanks for your help

You could try to make the applet bigger then the actual display to gain control over the graphics in the immediate surrounding of the original applet.

URGENT HELP IN SCROLLBAR MOVE TO BOTTOM

Joined: May 30, 2006

Dear friends,
I am using one Jtable in row also scrollbar .And requirement is while adding each row the table row and scroll bar will go to last row automatically.
I atried below code.
m_jTable.scrollRectToVisible(m_jTable.getVisibleRect());
m_pane.scrollRectToVisible(m_pane.getVisibleRect());
But some times the scrobar and bottom has a very small gap.
If anybody has any idea please share with me .

It is still there and Logic did not remove it.
Did you do some trouble shooting.
Try to load a different video (with different codec) to see if it is video file related
Try a new (empty) project to see if it is project related
Try to remove Logic preferences (move the original back if this wasn't the problem because the file contains other info you might not want to lose)
Hope that helps

Applet smudging while scrolling in Firefox

Someone else surely to God must be getting this problem. Its pretty unacceptable for a commercial application so everybody who programs java must have a workaround so come on what is it!!
If you take a page in firefox that has an applet and scroll up and down, tags in the background get smudged.
http://www.thepageuk.com/index.php/orderashowreel/emailconfirm/C22CbbpW
I think this should work. Scroll up and down in firefox and see the damage done to the surrounding area!

There he goes with the insults again.
Tell you what, thanks for trying, but don't bother. You're as annoying to me as I obviously am to you.
I probably am not as competent as you at Java. I have worked on a lot of stuff such as Burnout Revenge for Criterion, Stuart Little 2, 3 for games consoles, Treasure Planet Cat in the Hat, Buzz for MagentaSoftware. And I am one of two developers working for Articad Ltd which has the major share of Kitchen, Bedroom and Bathroom design software market. One of two means I have a massive influence on the company (I've been there for four years now), so if I was not reasonably competent I doubt I'd be in that role.
If I am lacking in Java experience its only because I dont specialise so much, and to be honest I do find the deployment aspects of Java immensely boring and unnecessarily complicated. I'll never change that opinion.
You just said yourself with your own words. "Although this Ubuntu machine is running 1.6.0_14, I have not managed to coax the browser into recognising the plugin2 technology. Although I have been meaning to look into it, I have not found the time.".
My thoughts are that these things should not need to be looked into. It distracts from the real aspect of development, the software itself.

Help!!!!!!!!!!a bug in my applet

i wrote a java applet,it compiled successefully ,but when i viewed it in IE brower, i found it doesn't reach my aim,my aim is :whem i push the scrollbar the position imformation will appear in the text field,and the two vertical(horizoncal)scrollbar always moves together,what is wrong with my applet,can you help me?
the source code is here:

Getting distortion in my movies in iDVDi

I am saving out .mov files from Final Cut 720 x 480.
They display correctly in my Quicktime player.
When I import them into iDVD the videos appear with a black bar top and bottom and the video is distorted- stretched. Does anyone know why and how to fix it?

So, turingtest2 has it exactly right... Unwatched movies view is sorted by Album Artist. So here's a nice little fix for that... you can go through and manually copy the Name of the movie into the Album Artist field, but if you have a lot of movies in this category, it will be tedious. A better option, is to go to www.dougscripts.com, and download the This Tag, That Tag applet. You can find a link here. You can then select ALL of your unwatched movies, run the applet, and elect to copy the movie Name into the Album Artist field. Boom! And since Doug has done such an awesome job of saving you a bunch of time and effort, throw him a little donation.
Peace,

Scroll bars of PDF files in browser do not move, nor does grab hand

This question may appear twice due to crazy site behavior.
Upgraded to FF4, broke pdf viewing: scrollbars move only if CLICKED in the clear area. Cannot be slid, and grab hand has no grip so can't move view that way either. Site links open pdf's in browser, so very inconvenient. Pdf's outside work fine, as did FF3.6. Using PDF-XChange.

Getting hold of browsers document object, from an applet

Well, at least that's how i think the problem will be solved.
The purpose is to insert some text into a hidden field on a form in the html where the applet is embedded.
so that this can be submitted along with the rest of the information that is entered through that page.
i've been looking at the AppletContext but i don't think this will provide what's necessary.
an alternate way of solving this would be to make an http-post with the information, since i prefer using our webserver to perform this.if this is the only way, is there a http-post object i can use for this, from an applet?

One way is to move the entire form into your applet so that it can do a post and send all the data itself (or vice-versa; avoid using the applet).
Another option might be to do it in two steps, have your form on one page then post all the details to the next page which contains the applet.
The only other option I can think of is to use JSObject to call a javascript function. Look at this link http://java.sun.com/products/plugin/1.2/docs/jsobject.html

How to make graphics in Applet not to repaint after I click "refresh"

Hi, pals
I have some interactive graphics inside an Applet. User can drag and
move the graphic objects. The problem is when user click "Refresh"
button of the web browser, those objects return to their original
positions. What I hope is to make those objects still lie on the new
position that user has moved them to after they click "refresh" or
"back" and "forward" button to return to the applet page.
do I need to write some thread control?
Think when you type new URL in the browser showing the applet and go to the new web page. The system will call
Applet.stop() and destory() to destroy the applet resource used by the
Applet webpage. When you go back to the applet page, the system will
call Applet.init() and start() to recreate it. All previous object
positions and states manipulated by user will return to original.
For example, there's a circle centered at (50,50), you move it to
center (100,100). Then you go to another webpage in the same web
browser frame. When you use "Back" button to return to the Applet, the
circle will be redraw at center (50,50). (why? because the browser call applet.init() and do all process as first time the applet download to your computer) What I hope is the circle still keeps
at its last center (100,100) . This seems impossible to me
since the applet has lost its memory about the center position
(100,100) last time when you go to another page and the system call
destory() to delete the applet.
Any suggestion?

I think you can disable page refreshing with javascript, but how, I do not know.
I wish this is helpfull.

In my Movies list, what order are movies sorted in when viewing the 'Unwatched' tab in grid view? Because it sure isn't 'by title' like I have selected. What gives?

Sample movie order:
The Adventures of Buckaroo Bonzai
Bella
No Country for Old Men
Breach

So, turingtest2 has it exactly right... Unwatched movies view is sorted by Album Artist. So here's a nice little fix for that... you can go through and manually copy the Name of the movie into the Album Artist field, but if you have a lot of movies in this category, it will be tedious.

Limit scrollbars usage to usefull area?

hello all,
I have been asked to restrict the front panel scrollbars to scroll the front panel not beyond the displayed component. How is it possible to do that in Labview (I use LV 8.0)?
I have this requirement because the user is able to scroll very far away from the front panel component and he might not be able to find again the displayed components easily.
Thanks in advance for your help.

I can simply not remove the scrollbar since the user must see 4 large graphs at the same time. It is OK on a 1280x1024 screen but I definitely need scrollbars on a 1024x768 display.
I thought that there was a built in front panel property to limit the scrollbars movement but as I can see in your answers, there is not.
The trick you told me in the example is not usable for me since I have around 100 components on the panel and I meet some Labview bugs when using clusters and picture of them (see my thread here: http://forums.ni.com/ni/board/message?board.id=170&message.id=212629).
Using the cluster is also a very bad thing for me since I will have to use property nodes in order to access individual items with some very very large arrays. The performance in my software is critical and I should not use any trick that need more power (even "unbundle by name" components are not efficient according to memory).
Thanks anyway for your answers

I have come to the conclusion that all applets are dysfunctional...

So yeah, I made my applet, and it is supposed to move an object by giving it a velocity in pixels per millisecond, and starting an animation loop, which moves it for 5 seconds.
So I do this, and everything is working fine after about an hour of coding. Then I decide to touch up my sprite image. I wanted to make it transparent, so I open up Photoshop, and do that. Now it doesn't work. Before I edited the image, the object would move to the edge of the screen, the game would check the boundary, and then reverse the velocity, so it stayed on screen. Now, when you tell the object to move, I can see that the x and y coordinates are changing, but the thing doesn't change on screen.
The applet itself is behaving very weird:
http://img62.exs.cx/img62/7140/whatswronghere9ur.gif
In the first frames, the applet loads up like normal, but there is supposed to be a button there, which no longer shows up.
In the second and third one, it shows that if you cover any part of the applet, it turns white, and just dissapears.
In the 4th one is what happens when you click where the throw button is supposed to be. What prints to the console are the x and y coordinates. So you can see the arrow is just supposed to move back and forth.
I just can't seem to understand why this worked intially but when I changed the image(not the path, I just opened it up and deleted the white background), the thing stopped working. I put everything back to normal, and it still won't work.
The main portion for the code of the applet is this:
http://www.freewebs.com/nickv360/problem/Physics.java
Here are the other classes(Which I didn't write BTW, so no credit to me for them)
http://www.freewebs.com/nickv360/problem/Sprite.java
http://www.freewebs.com/nickv360/problem/Animation.java
Those two classes along with the AnimationLoop algorithm were taken from a book, so yeah.
Can anyone tell me what happened here? (ALSO I'm not sure if this is in the right place, so if it's not, just point me in the right direction).

The only thing that changed was the size of the
image. I made it a bit smaller. But after seeing
that it didn't work, I changedthe image size back,
with no luck however. I am using the java sdk1.5 ,
the latest one. I find it humorous that you won't
believe me, even though I am telling the truth. I
mean, there's nothing more to say on this. I've got
no reason to lieI do not believe that anyone accused you of being a liar, but expressed some doubts towards your conclusions.
The fact of the matter is that lots of people post their problems here and blame it on java itself ('java is broken') etc... and more often than not, the problem lies in their code.
I guess the next thing to do would be for you to post your code here.

Need help with drawing shape and scrollbar

Hi everybody, I am newbie at java just started learning it. I have a few questions to ask.
1. Can anyone show me to how to draw a equilateral penatgon, octagon, ( 5-10 sized shape) with polar cordinate.
2. How to make the scrollbar back to their default state( work alone not together) after you use the "scrollbar1.setModel(scrollbar2.getModel())" method. For example I only want the scrollbar to work together when I choose circle as a shape after that I want the scrollbar to be back to normal when I pick another shape rectangle for example. When the scrollbar work together, how do I the make it so that the scrollbar move from bottom to top for vertical bar and from left to right for the horizontal bar when they work together instead of the default bar move from left(0) to right(max) for horizontal bar and from top(0) to bottom(max) for the vertical bar.

One more scrollbar question...

I have a JTable 'embedded' in a JScrollPane. The table is wide enuf and hence the horizontal scrollbar
is always present. The problem is, whenever I click on the table the horizontal scrollbar moves accordingly.
I dont want this to happen. I should be able to move horizontally ONLY using the respective scroll bar.
Any one knows how to do it ?
Thanks.

Hi Codekin,
To address your first question, the best way to create a tooltip type of message would be to register the PlotMouseMove event. This event will fire everytime you move the mouse cursor over a plot. You can then create a callback function which you can use the X and Y coordinates, which the event provides, and display them any way you desire.
Unfortunately, you can not add a Horizontal Scroll Bar to the graph control. On the graph tab of the properties, there is Track Mode selection which allows you to decide what to do with the graph as the data leaves the original screen. Although none of these allow for a scroll bar, you should be able to find the best behavior by playing around with these values.
This should get you on your way, but if you have any additional questions whatsoever, please repost and I'll get back to you as soon as I can. Thanks and have a good one.

Precompile jsp on nt move to solaris

          After useing weblogic.jspc to compile the applets on NT/2000, you cannot move them
          to the Solaris env. NT/2000 uses all lowercase when generating directories and
          java file names, but Solaris uses mixed case.
          Is there any way around this?
          P.S
          The build process is being done on NT/2000 because I cannot find a way to sign
          applets for IE on Solaris.
          Thanks,
          Mark


mark,
          i have had some luck in doing exactly the same thing. the key being putting
          the compiled classes under the WEB-INF/classes/jsp_servlet directory before
          taring up the webapp. this works well, however i've noticed that the
          solaris box still recompiles the jsps in the root directory of the webapp
          (ie. /index.jsp would always get recompiled although /foo/bar.jsp would
          not).
          any suggestions would be helpful.

Applet can't be loaed

Hi,
I want to invoke an applet from jsp page.
my jsp page is like this:-
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h2>Hello World!</h2>
        <jsp:plugin type="applet" code="EchoApplet.class"
        width="200" height="200">
<jsp:fallback>
      <p> unable to start plugin </p>
   </jsp:fallback>
</jsp:plugin>
    </body>
</html>My applet code is like this:-
public class EchoApplet extends Applet {
public void init() {
setLayout(new GridBagLayout());
// add title
Label title = new Label("Echo Applet", Label.CENTER);
}When I run the application, it shows "Loading Java Applet failed" in status bar. Please help me.

no there is no error on server log.
When i run the application it just displays jsp page with status "Applet MyApplet Notinited" but when I move mouse cursor over the applet status becomes "Loading MyApplet failed".it is responsiblity of borwser not server to load the applet class, apparently your server wouldn't throw any error/exception.
usually, it is a good strategy to jar your applet class files and then try loading in web browser. because it makes loading faster and lessen the confliction of assigning the correct path for applet class to codebase attribut of applet tag.
so try this
1) package you applet class files
    package mypack;
    // your applet class 2) put your applet class file in a folder named mypack. if it's already not in.
3) put this folder in bin directory of your jdk. C:\Program Files\Java\jdk1.6.0_02\bin
4) open DOS and write following commond
jar cf myjar.jar mypack/5)put this myjar.jar in the same directory, your jsp file is in.
now use this
     <applet code="mypack.yourapplet.class" archieve="myjar.jar"></applet>cheers
